Archived: the OG noob question thread! 😀

[drone001]

How much does your board weigh…My setup seems like it’s about 50+ lbs.

[JoelM]

If I have two single 4.12 vescs connected via CAN bus, can I use both uart ports? One for the remote and one for a davega display?

@Sigmur

I want a reliable 5V output from my battery to add a 5V 2A USB charger, front and back lights and other stuff on my board, so the 5V1.5A output on the ESC won’t be enough.

Use this guy

There are some extremely compact and highly efficient DC-DC converter modules out there designed for railway applications and the like, such as this tiny monster. 18-72v in, 5v 10a out, and up to 91% efficiency.

It’s even cheaper than that aliexpress item you linked, at a fraction of the size - 33.0 x 22.8 x 9.5mm.

Is the vesc-project page working for people? It’s completely dead for me. If possible, can someone direct me to some other firmware versions?

[Excess]

This what you’re looking for?

Precompiled VESC Tool Archive

Since each build of the VESC Tool is compatible with only a few particular versions of the VESC Firmware, every now and then we find ourselves searching around for a place to download a precompiled executable of one of the older versions. When faced with this situation you either have to find it by googling, ask around on the forum, or download the source code and compile it yourself. All of these take time and can turn a simple task into a real pain. To remedy this, we have decided to crowdsour…

[annihil8ted]

Thank you! But also on a separate note, is vesc-project down and if so why?

[Excess]

Not loading for me either. Maybe maintenance or something.

[annihil8ted]

Thanks for confirming! I think it’s been down all day. I tried earlier this morning and still nothing

[b264]

If you are looking for Vedder version 4.1 and OS Linux, then I have a copy.

I also have Ackmaniac 2.54 for Windows and Linux and mac something

I also have Ackmaniac 3.103 for Windows (the Linux version is broken)

I mean if the site is down and you need something now.

[Scepterr]

we need a repository here

[b264]

You can also go to github and download the source and compile it yourself but that takes longer than asking for it.

[b264]

Oh here is Ack 3.102 built for Linux

[migimogi]

anyone know where i can buy replacement batteries from riptide boards? they are currently sold out on their website. preferably the R1X

[xsynatic]

Yes you can

[annihil8ted]

Having issues programming my remote. Remote programs and tracks fine while programming with the vesc tool but afterwards, the smallest throttle input results in 100% throttle. Any ideas?

Look at Duty Cycle, it just seems to automatically ramp to 100.

[Alpacaslapper]

Anyone using this bms?

[Sigmur]

There is a thread on these, it’s not a BMS, it’s a charge balancer

Testing active balancer - results

Ordered one of these through ebay, got it in a couple weeks ago: [image] It’s an active balancer, started talking about them here: Put it through some cycles and wanted to share my findings. A bunch of numbers: [Untitled] Tested on a 12s pack that was being fixed. Manually drained cells 5, 6, and 11 down to a voltage where bms balanding would NOT work (bms won’t go into balance charge if delta is ±0.075v or so). Starting voltages, out of balance cells in RED Drained pack down, varianc…

I want one myself

[Alpacaslapper]

Thanks, kinda misleading they put bms in the title.

So it’s a Balancer, what’s the difference between this and a bms that balances? My first battery had the bms preinstalled, my second battery was just a temporary one the bms was damaged it was 10s2p so I just removed the balancer and ran it. My battery I’m building now is 10s1p. Trying to find a direction with bms/balancing. Budget and space constraints in mind.

[tipsy]

This will only do balancing. You don’t charge through it and you don’t discharge through it.
I have one and did some test with it; didn’t like it.
The balancing accuracy is pretty low. It will keep your highest and lowest P-groups within ~100mV, pretty bad.

edit: If space is limited, consider doing external balancing with no BMS/PCM onboard at all, that’s what I’m doing. Less stuff to break in the board too.
